lab 20 - libmux

NAME

DESCRIPTION

To learn about mux in detail I tried to implement
libmux in limbo. It actually resembles the mux
from libventi more than libmux. They are pretty
similar.

I was going to do a detailed description of the
mux in devmnt but it turns out this has already
been done here by nemo.

When I get this working it can be applied to the
venti lib for session rpc, to build a libfs for
direct client 9p interaction, bypassing devmnt,
and for application protocol muxing, say for sam.

This is a partial implementation. I didn't
complete send, recv, gettag and settag functions,
so this has not been tested. I'm just posting it
here now so I don't lose track of it. I'll come
back to it later, maybe writing more for the Venti
library or libfs. This is more an excercise to
understand the workings of libmux and venti's
session rpc.
